Review findings

The core P/E and P/B formulas are standard under the per-share price assumption, and EV/EBITDA is standard once EV is supplied with matching units. The specification fails because P/S is omitted, EV is not declared as an input, and peer comparison has no formula or methodology. The educational-only and not-a-buy/sell-signal label is appropriate but does not resolve these mathematical and input-definition gaps.

Formula and scope findings

  • P/S is claimed as an output but no P/S formula is provided; the standard formula is price_per_share/sales_per_share, equivalently market_cap/total_sales.
  • EV/EBITDA=EV/EBITDA is mathematically correct but the required EV input is missing from the declared inputs.
  • Peer comparison and peer delta bars have no defined calculation, including no specified peer aggregation method, baseline, or sign convention.
  • The meaning of price is ambiguous: the listed P/E, P/S, and P/B formulas require price per share, not total market capitalization or enterprise value.

Unit assumptions

  • price, EPS, sales/share, and book value are all denominated in the same currency per share and over the same reporting period where applicable.
  • EV and EBITDA are both total-company values in the same currency and reporting period.
  • P/S is assumed to mean price per share divided by sales per share; alternatively, market capitalization divided by total sales produces the same ratio only when the share-count basis is consistent.
  • Ratios are dimensionless.
  • The numeric outputs below use the standard P/S formula even though that formula is missing from the specification.

Boundary hardening

Recorded hazards

  • Division by zero occurs when EPS, sales/share, EBITDA, or book value per share is zero; the implementation needs explicit undefined/error handling rather than Infinity or NaN.
  • Negative EPS makes P/E negative and typically unsuitable for ordinary multiple interpretation; negative or zero book value, sales, or EBITDA also requires an explicit labeling policy.
  • EV must be defined consistently, typically as equity value plus debt plus preferred equity plus minority interest minus cash and equivalents; omitting components can make EV/EBITDA misleading.
  • Period mismatches between price/EV and trailing or forward financial metrics can produce invalid comparisons; the period basis must be explicit.
  • Peer deltas are undefined without a specified reference statistic such as peer mean, median, or selected peer, and without a sign convention.
  • Currency and scale mismatches, especially cents versus currency units or thousands versus millions, can produce materially incorrect ratios.

Inspectable example

4 review vectors are recorded. One source-bound sample is shown below.

    "price": 60,
    "EPS": 3,
    "sales/share": 24,
    "EV": 900,
    "EBITDA": 150,

    "P/E": 20,
    "P/S": 2.5,
    "EV/EBITDA": 6,
    "P/B": 2
  },
  "working": "P/E = 60 / 3 = 20. P/S = 60 / 24 = 2.5. EV/EBITDA = 900 / 150 = 6. P/B = 60 / 30 = 2."
